Application filed February 26, 1914. Serial No. 821,118.

T0 all whom t may concern.' l

Be it known that l, CHARLES 1V. Horr- MANN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Sausage-Stuer, of which the following is a specification.

My present invention consists of a novel sausage stuner, wherein novel means are provided forcausing the sausage or other material to pass into a skin, bag or other receptacle, under any desired or predetermined pressure.

lt further consists .of a novel sausage staffer, in which novel means are employed to effect the discharge of the material from the machine.

1t further consists of a novel construction of feed blades, and novel means for automatically cleaning the saine during the operation of the machine.

.lt further consists of a novel manner of causing, at predetermined times, a partial rotation of said feed blades. Y

lt further consists of a novel construction of a shoe or slide, and a novel con struction of tracks coperating therewith.

It further consists of a .novel construe-I tion and arrangement of a tension device, and a valve controlled thereby.

It further consists of a novel construction of a casing and coperating parts, and

vother novel features of construction, all as will be hereinafter specifically set forth.

For the purpose of illustrating my invention, 1 have shown herein a preferred embodiment thereof, which in practice will give satisfactory and reliable results, although it is of course to be understood that the various instrumentalities of which my invention consists can be variously arranged andorganized, and that my invention is no t V.limited to the exact arrangement and organization of these instrumentalities, as herein set forth.

Figure 1 represents a side elevation of a sausage stuffer embodying my invention. Fig. 2 represents a plan View thereof. Fig. 3 represents a plan view of the casing having certain of the operating parts removed. Fig. 4i represents a plan view of a cover plate and cam supporting members. Fig. 5 represents, on an enlarged scale, a sectional elevation of'a portion of-inyv device, the section being taken on line zz-, Fig. 2. Fig. 6 represents a plan view, showing a portion-of my device. Fig 7 represents a section on line g/-g/ of Fig. 6. Fig. 8

Similar numerals of reference indicate corresponding parts in the-figures.

Referring tothe drawings: 1 designates standards or a ysupporting framework, constructed inany desired i manner, and in.

which is journaledv a main driving shaft 2,

which is driven by any desired ,source of` power, or manually, if desired, and forv purposes of'illustration I have shown saidV shaft 2 as beingprovided with the pulleys 3, whereby the latter are adapted to re-V gear 7, which is fixed on asleeve 8, loy-v means of a setv screw 9, said sleeve 8 being loosely mounted lon the shaft 6.. The

sleeve 8 is journaled in the `bottom casing 1 member 10, which latter has removably connected therewith, an upper casing member 11, the upper portion of whichforins av hopper 12. The bottom casing member 10,

4as best 'seen in Figs. 3, 6 and 7, is provided with a track 13, one end of which isl beveled or inclined, as indicated at 14e, at, which point the annular track 13 is-cut away orv interrupted, as will be clearly understood by reference to F ig. 3.

15 designates a second track, theends of which are inclined or beveled, as indicated at 16 'and 1'7, respectively. The bottom casing member 10, isalso preferably provided with an annular groove 18, which.

is adapted to receive the bottom rib 19, of a ring or annulus 20, which latter is -provided with an annular toprib 21, which is adapted' to be seated in an annular groove 22, of a cover plate 23, which latter is secured to the casing member 10 by means of fastening devices 24. The cover plate 23 is provided with a central portion 25,

and is cut away 'as indicated at 26 and 27, in order to permit the material to pass which are adapted to travel in the channel l 28, and between the side of the casing member 1Q and the` annulus 20, and the top and bottom portions of said paddle` are preferablyl rounded, as will be best understood by reference to Fig. 5., 'and Fig. 6. Each feed blade or paddle 32 is provided with a stem 33, which passes through the annulus 20, and has its inner end journaled in a hub 3,4, which is fixed to the sleeve 8, b y means of a key 3.5, whereby said hub and said sleeve r0- tate in unison. For convenience of illustral tion, l. have shown the annulus 20 as pro vided with apertures 36 through which said stems 33 extend, but it is within the scope of my invention to. form the annulus 20 in separate parts instead of in one part.

37 designates a shoe which is apertured as at 38, in order to permit a stem 33 to pass therethrough, said shoe being fixed to its respective stein, inthe present instance, by means of a pin 39, although if desired this shoe may be cast integral with the stem 33 and its, blade 32. Each shoe 37 is provided with an upwardly extending portion`40, preferably having a rectangular contour, and said shoe is also provided with a laterally projecting portion 41, which is also preferably of a rectangular contour. The lug or projection 41 of a shoe, travels between the tracks 13 and 2.9, while the lug 40 coperates with the tracks. 1'5 and 30.

42 designates a delivery spout having lugs 43, whichV are adapted to interlock with the groove 44 of: a spout 45 which is preferably provided with a conical end, thereby adapting the same tobe received in a skin or casing which is toY be filled.

46 designates an actuating handle for locking the spout in assembled position. By such construction spouts of different sizes may be ereadily removed or. connected with respect to the discharge opening from the machine.

47 designates a block secured to the bottom casing member 10, by means of fastening devices` 48, ofy any desired type. said block having a curved side face 49, the forward end offwhichY is in alinement with the wall of the dischargev `spout 42. The upper wall of saidblock 47 is preferably substantially flat as indicated at 50, so that whena feed blade 32 isv passing thereover, it will pass in close proximity to said upper wall 50, which latter will serve as a cleaning means for one side of said blade.

51 designates a valve member, the lower end of which normally abuts against the side wall of said block 47, said valve member 51 being carried by a rod 52, journaled in the casing member 10 and the annulus 20. rlhis rod or shaft 52 extends exteriorly of the casing and is internally threaded in order to receive a manually adjustable screw 53, on which latter' is provided the pins 54, which position a collar 55 so that the latter is prevented .from relative longitudinal movement with respect to the screw 53.

56 designates a spring, one end of which is connected with a collar 55, while the otl er end thereof is connected to a fixed point, such as for example the pin 57. The adjusting screw 53 and the spring` 5G, and their adjuncts, form an adjustable tension device for the valve member 51, and thereby regulate the pressure under which the material passes through the delivery spout 45 into the skin or casing which is being lilled.

is best seen in F ig. 7 the plate 23 is provided with a hub 58, having a key 59 (see Fig. 6), which latter interlocks with a recess in the hub 60, to which latter is secured a stirring or agitator blade 61, and in the present instance these blades are integral therewith, and tend to feed the material downwardly into the feed channel. rEhe annulus 20. is connected with the hub 34 by means of the arms or spokes 62.

The operation of my novel sausage stuifer will now be. readily apparent to those skilled in this art, and is as follows: rlhe sausage or other material which is to be packed into the, skin or casing, is placed in the hopper 12 and the driving shaft 2 is actuated in any desired manner, and owing to the construction and arrangement of the gears 4, 5, and 7, the mixing or agitating blade 61 will be revolved in one direction, while the feed blades 3,2 will be revolved in a reverse direction. rif'he material feeds down between the blades 32, as will be understood by reference to. Fig. 2, so that the. material is fed through the lchannel 28, beneath the plate 23.` 'A slide or shoe. 37, has one of its operative faces, such as for example the lug orv extension 41, positioned to travel between the tracks 13, and 29, which will cause the feed blades 32 to assume a vertical position during their revolution, but as soon as the lug 41 reaches the beveled or inclined end 14 of the .track 13, the lug 40 passes up the incline space 16 on to the track 15, thereby bringing a feed blade at such time into a fnibstantially horizontal position. The material, such as for example the sausage, passes out the stationary discharge spout or opening 42, and through the removable discharge spout or opening 45, and into the skin or casing, which is to receive the sausage. This action is caused by the curved face of the block 47, so that the sausage or other material is guided into said Yopening 4:2. It will be noted that the top wall or face of the block 47, is at such a height that when a feed blade is passing vthereover in a horizontal position it will travel in close proximity to such wall, so that one face of the blade will be freed of any sausage or other material adhering thereto. On the further advancement of the feed blade it engages the valve or door 51, causing the same to open against the tension of the spring 56, and since the lower edge of said valve or door 51 is in contact with the upper face of the feed blade 32 passing thereunder, any sausage or material adhering to such face will be removed therefrom.

Special attention is directed to the manner in which'l am enabled to pack the material in the skins or casings under any desired pressure, since the adjusting screw 53' may be regulated to vary the tension of the spring 56, so4 that Aat any predetermined pressure, the valve or door 51 will move toward its open position and permit the sausage or other material to pass therethrough, instead of forcing the same throughthe discharge opening d2. By such construction, l provide a safety or relief valve which prevents the material becoming packed too tightly in the skins or casings, and which prevents the bursting open of the skins or casings during the filling operation, since, as iswell known some skins or casings will stand a much greater pressure than others. As the lug or extension 40 of a shoe 37, passes down the inclined end wall 17 of the track 15, the lug or extension 41 of said shoe will again engage with and be guided by the tracks 13 and 29, asis apparent.

It will be understood that the annulus 20 rotates in unison with the feed blades, and if desired the upper and lower ribs thereon,

` 18 and 21 respectively, and their coperating recesses or grooves may be dispensed with, since their only function is to form a better fit between the bottom of the casing 10 and the top or cover plate 23, so that there is less likelihood of the material passing between said annulus and said casing 10 and said plate 23.

lt will now be evident that in accordance with my present invention, 1 provide feeding or conveyer members which during a portion of their revolution travel in an upright position, and which when they arrive in proximity to the discharge opening, are automatically partially rotated, in conjunction with novel means for regulating the pressure on the material, so that such material may be passed into a container of any desired type, at a desired pressure, and I also provide novel means for removing from a feed blade any material which` adheres' It will now be apparent that have de` vised arnovel and useful construction of a sausage stuffer which embodies the features of advantage enumerated as desirable-1n the statement of the invention and the above de-V scription, and while 1 have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results', it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
